94 GHz InP MMIC five-section distributed amplifier

Abstract

A single-stage 94 GHz InP MMIC amplifier with 6.4 dB gain at 94GHz has been developed, which is the highest frequency MMIC amplifier reported to date. Lattice-matched GaInAs/AlInAs HEMTs with 0.1μm mushroom gates were the active devices. The CPW MMIC chip dimensions are 500μm × 670μm.
